The Weak Signal Propagation Reporter Network is a group of amateur radio operators using K1JT's MEPT_JT digital mode to probe radio frequency propagation conditions using very low power (QRP/QRPp) transmissions. The software is open source, and the data collected are available to the public through this site.

Heard IW4EGP using 5 Watts on 10m during a sporadic E opening at a distance of 7562km. Here are the spots of all the stations hearing IW4EGP JN64gb at 1452Z on 2019-06-21.

I haven't posted here in a while!

To help encourage more WSPR activity on 28 MHz, I will be on receive only from time to time during the Summer of 2019.

I usually monitor the FT8 frequency most of the day and feed the spots up to the PSK Reporter website. I have my radio set up now so that it's easy to switch to the WSPR frequency and feed those spots to the WSPRnet website.

I'll probably do this by listening for WSPR signals for 10-30 minutes at a time when the band seems open before going back to FT8.

Hellow fellows 73 to all i will make portable operante vertical 20m test nem antena 10m wire and 16 radiais 1/4wave lets see um 1h tks hope all good 73/dx PY1AX tony

My shack like most peoples I guess, is always in a temporary state.
My new purchase is an 2003 Elecraft K2 which lends itself well to Wspr. Probably the most frequency stable rig I have owned. The uBitx/TS120S hybrid is now on the shelf unused and the FT757 GX II is the back up rig now connected up and still used most days.
I now have a dedicated 30 metre dipole, so I have an antenna for every HF band plus 160 metres.

Icom 7300, attic dipole - transmit, amplified loop - receive

МАЯК Р=1ват. (WSPR-2) Маяк сделан на ARDUINO -NANO и запрограммирован на основе информации с сайта прошивка для моего позывного сделана US3MW. Мощность увеличина до 1вата и все диапазоны с автоматическим переходом на каждый диапазон по кругу. можно отключить любой диапазон .Работает на длинный провод 65метрров.

There's a bit of remodeling and reorganization going on, and I need to relocate the Raspberry Pi and co-ax that runs the beacon. Will be QRT today. Might off be a day.
Carry on,

PS. Back on line, and with 70 feet less co-ax, too. Still, a hamster could generate more than 10 milliwatts, but it's amazing what WSPR can do.


Ok, finally built the club project kit. First tried an untuned long wire. Currently using my dipole so will leave it running over night.

I think got call sign word set. What equipment do I need to Hook to my computer. So I can get going?
Or do I have the wrong settings.?

I am in the process of seting up my station as well as QRZ and eQSL accounts. I am absorbed in various experiments. Recently was climbing trees with my antennas.
Still waiting for SignaLink USB and some cables. So far my phone squeaks into microphone of Yaesu FT-818. The reception is on other bands with a separate antennas and SDRplay connected to the computer.
At the rural location of my station there is extremelly weak internet connection, hence some actions must wait. Everybody who is waiting for eqsl please forgive. I will send it a bit later. now fine. The trick: add your user to the group "dialout". Antenna is still the selfmade "Springy" indoor antenna as mentioned before...

We are very excited to announce the RFzero - a multipurpose Arduino RF platform that can do WSPR from 100 kHz to 1 GHz in a cost effective way and at the same time with a responsible RF spectrum and stability performance.

You can use one of the dozen example programs or tweak them to fit your specific need for WSPR but also for CW, FT8, JT9 or PI4. Soon we will also have an example program for a QO-100 dual LO solution.
